| | 84 | The tutorial directs me to configure one-way (OWAMP) and round-trip (Ping) latency regular tests according to the following diagram. |
| | 85 | |
| | 86 | * Accessed psConfig UI |
| | 87 | Image |
| | 88 | * Enabled services on pca, pcb, and pcc and pushed configuration to UNIS |
| | 89 | Image |
| | 90 | * Configured regular active measurements according to diagram (above) and pushed configuration to UNIS |
| | 91 | Image |
| | 92 | * Applied configuration to the nodes |
| | 93 | Image |
| | 94 | |
| | 95 | === Execute the reference experiment === |
| | 96 | * Started the iperf server on PCC |
| | 97 | {{{ |
| | 98 | [johren@PCC ~]$ iperf -s |
| | 99 | ------------------------------------------------------------ |
| | 100 | Server listening on TCP port 5001 |
| | 101 | TCP window size: 85.3 KByte (default) |
| | 102 | ------------------------------------------------------------ |
| | 103 | }}} |
| | 104 | * Started the iperf client on PCA |
| | 105 | {{{ |
| | 106 | [johren@PCA ~]$ iperf -c pcc -t 120 -i 12 |
| | 107 | }}} |
| | 108 | * Started the Phoebus gateway on PCB |
| | 109 | {{{ |
| | 110 | [johren@PCB ~]$ sudo /etc/init.d/phoebus start |
| | 111 | [johren@PCB ~]$ tail -f /var/log/phoebus.log |
| | 112 | }}} |
| | 113 | * Introduced network impairments |
| | 114 | * For this step I had to create an SSH key pair for user johren and install them in ~/.ssh/authorized_keys on PCA and PCB |
| | 115 | * I also had to set the SSH config in ~/.ssh/config to use the new private key when contacting these hosts: |
| | 116 | {{{ |
| | 117 | Host PCA |
| | 118 | IdentityFile ~/.ssh/phoebus |
| | 119 | Host PCB |
| | 120 | IdentityFile ~/.ssh/phoebus |
| | 121 | }}} |
| | 122 | * I then ran the "user" version of the setup_netem script |
| | 123 | {{{ |
| | 124 | [johren@PCA ~]$ sh /tmp/setup_netem_user.sh |
| | 125 | Setting PCA->PCB link to 5ms latency and .01% loss |
| | 126 | Setting PCB->PCC link to 50ms latency and no loss |
| | 127 | done |
| | 128 | }}} |
| | 129 | * Again, ran the iperf client on PCA |
| | 130 | * Enabled phoebus gateway on PCB |
| | 131 | {{{ |
| | 132 | [johren@PCA ~]$ setenv LD_PRELOAD /usr/lib64/libxsp_phoebuswrapper.so |
| | 133 | [johren@PCA ~]$ setenv XSP_PATH pcb/5006 |
| | 134 | }}} |
| | 135 | |
| | 136 | Insert picture of log here |
| | 137 | |
| | 138 | * Again, ran the iperf client on PCA |
| | 139 | * Stopped phoebus service on PCB and iperf server on PCC |
| | 140 | {{{ |
| | 141 | [johren@PCB ~]$ sudo /etc/init.d/phoebus stop |
| | 142 | }}} |
| 85 | | Right now, the presentation service is the web server on the UW. I observed the results by |
| 86 | | pointing the browser at http://localhost/oml.html |
| | 146 | === Observe passive measurements === |
| | 147 | ==== Observe sidebar graphs for each node ==== |
| | 148 | * For each node (PCA, PCB, PCC)... |
| | 149 | * click on node in Map view |
| | 150 | Insert image here |
| | 151 | * select graphs individually and make graphs show up on the left |
| | 152 | Insert image here |
| | 153 | * select All Graphs and make sure all graphs show up in separate tab |
